PAPER-BOX-COVERING MACHINE.

Specification of Letters Patent.

Patented Nov. 16, 1909.

T 0 all whom it may concern:

Be it known that I, CHARLES IV. IVIAC- DONALD, a citizen of the United States, residing in Philadelphia, Pennsylvania, have invented certain Improvements in Paper- Box-Covering Machines, of which the following is a specification.

My invention relates to machines designed for the purpose of covering box blanks with paper.

In machines of this class, a blank previously made of pasteboard or other material of the desired size and shape is applied to a support familiarly known as a chuck.

This structure may be adjustable to accommodate boxes of various sizes, and is rotatable so that when a strip or sheet of paper has been applied to a convenient part of the same, it may be turned to facilitate the engagement of the paper with the rest of the blank.

In the ordinary method of covering boxes, the operator applies to a portion of said blank, the end of a sheet of paper previously coated with paste whereby it may be secured to said blank. The paper having been applied to the sides of the blank, the latter is then ready to have such paper tucked in on the open side of the blank and pasted down upon the bottom of the same, thereby finishing the operation necessary to deliver a completely covered box. Box lids may be treated in the same way, except that a relatively narrower strip of paper will be applied, and the chuck supporting the cover, as well as the other mechanism will be relatively modified as to size, so as to act upon the same. The top of the cover then receives a rectangular sheet of paper to finish the same, and, if desired, a similar section of paper may be applied to the bottom of the blank.

The improvements forming the subject of my invention are designed to automatically present the strip of paper to the box blank; to automatically revolve the chuck carrying the latter when the paper has been brought into engagementtherewith; to automatically sever such strip of paper ;v to automatically tuck the projecting portion against the inside walls of the blank, and to automatically fold down the projecting portion of the paper against the bottom of said blank; the operator simply supplying blanks to the chuck and removing the same when covered.

In presenting my invention to the trade, it is my object to provide a machine that will avoid the great waste ofpaper usually accompanying the work of covering box blanks, and at the same time greatly reduce the amount of time and labor necessary to produce completely covered boxes in a neat and satisfactory condition;

The apparatus forming-the subject of my invention is a great labor saver in that it does away with the independent operation of applying paste to the paper, and the services of an operator for such work. The paper with which the blanks are covered is taken directly froma roll of'the same and the paste is applied in its passage therefrom; and not only in this way is labor saved, but also by reason of the fact that the apparatus I have designed is operated in triplicate; the several structures for carrying out the functions of my invention being mounted on a suitable revolving table, and intermittently actuated as said table revolves. Thus, while an operator is applying a blank to one chuck, the other structures are at work covering the blanks, so that three boxes are being turned out for every revolution of the table, and with the labor of but one operator. It is also possible to produce covered boxes of different sizes on the separate sets of mechanism.

Byhaving an automatic gluing device for the paper, a great amount of time is saved over machines which require the paper to be glued independently of its passage to the blanks and then transferred to the latter. A great amount of time is also saved by providing a machine capable of working on several blanks at the same time.

Other features of my invention will be pointed out hereinafter, reference being had to the accompanying drawings, in which:

In Fig. 1, of the drawings herewith, I have illustrated three complete apparatus made in accordance with my invention for covering paper boxes, mounted upon a rotatable bed or table. In such structure the automatic operations of applying the paper to the box blank and securing the same thereto may be carried on during the rotation of the table; the feeding of blanks and removal of the covered boxes being attended by a single operator. Referring to this figure of the drawings, 1 represents a rotatable base or table mounted on a vertical shaft or spindle 2, which may be driven in any desired or well known manner, (not shown), and may be provided with a ball bearing 3. This base or table, as above indicated carries three operative mechanisms of the type forming the subject of my invention for applying paper to the blanks, and for securing such paper thereto, to which particular reference will be made hereinafter. Each of these mechanisms comprises paper applying means, indicated at A; blank receiving and rotating means, indicated at B, and securing and turning in means for the paper, indicated at C. These several means for operating upon the box blank are driven respectively by the pinions 4:, 5 and 6, mounted on the shafts 4 5 and 6 which serve to transmit movement to the rest of the mechanism, and these pinions in turn are operated by the teeth of annular racks shown by dotted lines in Fig. 1, and indicated at 7 8 and 9. To prevent movement of the parts except when desired, these pinions have blank spaces for engagement with blank portions of the rack before and after they perform their necessary work. The rack 7 is much less in diameter than the racks 8 and 9, and is designed for engagement with the pinions 4 for operating the paper applying mechanism. The racks 8 and 9 are disposed at different heights so that they will be free to engage the pinions 5 and 6 independently of each other, the one for operating the chuck carrying the box blank as the paper applying mechanism is brought into position to pass the paper to such blank, and the other for operating the means for turning in the projecting portion of the strip of paper covering the box blank.

The paper applying mechanism is clearly shown in plan View, Fig. 2, in side elevation, Fig. 3, and in the several diagram views. This mechanism comprises first a traveling frame indicated at 10 having ribs 11 adapted to slide in ways 12 formed in the rotatable table 1, which ways'may be dovetailed. Mo tion is imparted to said frame by means of links 13 connected thereto at 11, and at their opposite ends at 15 to face pl ates-16 mounted on a shaft 17 carried by suitable bearings 18, and driven by the pinion 1 and shaft through the medium of bevel gears 19 and 20, from the rack 7. The rack 7 is of a length suflicientto rotate the pinion at one complete revolution so that the frame will be carried forward and back by such movement of said pinion.

Mounted on the revolving table 1 and disposed so that the frame 10 travels through the same, is an arched standard 21 having a bracket 22 supporting a paste receptacle 13, in which a paste roll 2st is arranged to rotate; said receptacle also carrying brackets 25 supporting a roller 26 from which the paper 27 is unwound. This paper passes over said paste roller; then over a guide roller 28 carried by the paste receptacle; then under a guide roller 29 carried by the frame 10, and thence is carried through said frame for engagement with the box blank. The frame 10 travels through the arched structure 21, and mounted on a rock shaft 30 jonrnaled in the same, is a yoke arm 31 having fingers 32 with upwardly extending points 33, projecting from the end of the same and lying normally adjacent the blank to be covered. The end of the paper to be applied to the box is engaged bv these points and maintained in such position until delivered to transfer means and from the latter to the box blank. The arm 31 operated at regular intervals by means to be described hereinafter.

Disposed within the frame 10, is a standard 35 having a base 36 with ribs 37 adapted to slide in grooves 38 in the table 1, which standard is actuated by the frame 10 at the ends of its reciproeative movement; in the one instance to carry means holding the end of the paper to the box to be covered, and in the other instance to return said means to the original position for fresh engagement with said paper. For this purpose said base 36 is provided with side rojections 39, and the frame 10 is slotted at 4-0 for the accommodation of said projections, the ends of said slots engaging the latter and imparting movement in each direction to said standard.

in Fig. 7, the frame 10 is shown as moved to its full extent toward the chuck carrying the box blank, together with the standard which carries the transfer mechanism for engaging the paper and taking the same from the points of the fingers 32. The upper part of the standard 35 carries bearings -l-1 for the passage of rods 42 having a cross piece 43 carrying fingers t t with downwardly projecting points a5, to which the paper is to be transferred from the points 33. The transfer mechanism is actuated by the rear 'ard movement of the frame 10. Disposed adjacent the standard 35 and mounted in its base is a vertically movable rod 46 having projections 47 for engagement by cam slots 48 formed in the side walls of the frame 10. i-rs said frame is retracted, the projections 4-7 are carried by the cam slots in an upward direction, which moves the rod toward the points 33 of the fingers 32 carrying the paper. This rod also carries a step or projection 49, and as it rises, said step engages the end 50 of a bell crank lever pivoted at 51; the opposite ends 52 of said bell crank lever engaging the cross piece 4-3 connecting the rods a2; thecontinued movement of said rod pushing said arms rearwardly so as to bring-the fingers H with their points 45 directly over the upper por tion of said rod 4L6. This portion of the rod is channeled at 53 for the passage of the fingers 32 having the points 33 in engagement with the paper and said portion serves to strip the paper from said points and apply it to the points 4-5 of the fingers 44. As the frame 10 continues its rearward movement to the position shown in Fig. 9, the rod 46 descends under the control of cam slots 48 of the frame, and this movement releasing the bell crank lever, permits said rods 42 to be carried forward with the points 45 of its fingers 4:4 in engagement with the end of the paper until the latter is brought directly over the ed e of one of the box blanks as shown in Fig. 10, and it is then ready to be applied to said blank.

For the purpose of attaching the end of the paper to the edge of the box blank, I provide vertically movable gripping mechanism mounted in the base of the standard This mechanism comprises a table 55 to engage the under side of the blank, and a stripping or presser member 56 to engage the upper portion of the blank for removing the paper from the points as of the fingers 4a in its action and thereby securing it to the box blank. This mechanism is normally upheld by means of projections 57 of the member 56 adapted to cam slots 58 in the side walls of the frame 10. lvhen the frame moves rearwardly a slight distance beyond the position shown in Fig. 9, these projections come opposite vertical portions 59 of said cam slots and then the members 55 and 56 will be operated. This is accomplished by means of a spring 60 nor mally compressed by the inactive position of said members, and this spring serves to directly raise the table or support In order that this movement may be communicated to the member 56, I provide pinions 61 for engagement with racks 62 and 63 carried by said members, whereby the upward movement of the member will cause downward movement of the member 56. The stripping or presser member 56 is notched at 64c to pass the fingers a l, and in Fig. 10 this member is shown just after it has secured the paper to the box blank. The frame 10 is now retracted to the full extent as shown in Fig. 3, restoring the standard 35 and its operatively connected parts to the normal position, ready for fresh ei'igagement with the paper when another blank is to be covered. 4

The form or chuck to receive the box blank is indicated at 65. The end of the paper strip having been applied thereto in the manner indicated, the mechanism which has been employed to attach the paper there to is retracted until it is necessary to apply said paper to a fresh blank, leaving the fingers 82 with their points 33 in position ready for fresh engagement with the end of said paper strip. The form or chuck carrying the blank is then revolved until the paper has been applied to all four sides of said blank and then the paper is cut, and the last edge of the paper in engagement with the box is smoothed down. The form or chuck 65 is carried by a shaft 66, rotatably and slidably mounted in a bearing 67 and driven by a pinion 68 from a gear wheel 69 mounted on the shaft 5 which in turn is driven by the pinion 5 operated by the rack S. Disposed adjacent the chuck 65, is a hollow plunger 70 which serves to turn 111 against the inner wall, of the box blank the paper projecting at the open side of the same; the chuck carrying the blank being movable against said plunger for this purpose.

To cut the paper after it has been applied to the blank, the following means are em ployed: Referring to Figs. 8, 4, 16 and 17, 71 represents a lever pivoted at 72 to the supporting base of the bearing 67. This lever 71 is in turn connected to a lever 7 3 pivoted at 74 on the side of the plunger 70; the opposite end of said lever being connected at 7 1 to a rod 75 adapted to slide in a casing 76 having a flaring mouth 77. A pair of blades 78, normally held apart by a spring 79, are connected at 80 to said rod 75. When the rod 75 is retracted, the blades 78 will close, shearing the paper, and the mechanism for closing said blades is operated in a manner to be described.

In severing the paper, the shears cannot, of course, come closer than the width of the blade nearest the blank, and such cutting of the paper leaves a short edge to be turned down against the box, and this is accomplished by said blade in its final movement after cutting the paper. To render this action as easy as possible, such blade is provided with a smoothing surface 81 which is so arranged that it will not disturb the portion smoothed down when the blades are opened upon the retraction of the frames. The shears also carry means for insuring engagement of the end of the strip of paper with the points 33 of the fingers 82 carried by the yoke arm 31. Such means consists of a guard 82 pivoted to one of the blades and overlying the other blade; said guard being provided with a groove 83 arranged to lie directly over the points 33 of said fingers when the paper is severed. As the blades come together, the end of the paper will be pressed onto said points by said guard in the manner shown in Fig. 18.

After the paper applied to the box has been severed from the length extending from the roll, it is necessary to raise the yoke arm 31 carrying the fingers 32 having the points 33 in engagement with the end of the paper strip. Numerous ways of accomplishing this may be employed, one of which is shown in the accompanying drawings. The yoke arm 31 is carried by the rock shaft 30 to which movement is imparted to raise said yoke arm so that the frames St and 85 carrying means for turning in the projecting edges of the paper and for turning down the portion on the bottom of the blank can come forward to perform their work. Carried by the arched standard 21 is a bracket 86 having bearings 87 for a shaft 88; said shaft carrying at one end a pinion 89 and at the opposite end a bevel gear 90 for engagement with a bevel gear 91 carried by the rock shaft 30. To actuate this shaft the frame 84: carries a rack 92 for engagement with the pinion 89 when said frame moves forward, and this motion being imparted to the bevel gears 90 and 91 by the shaft 88, the yoke arm 31 is raised over the frames 84 and 85, the front one of which carries a guide-way or guard 93 for engagement therewith dur ing this movement. hen the frames are retracted, the pinion 89 is turned in the opposite direction until the yoke arm 31 has been restored to its normal position. During this movement of said yoke arm, the fingers 82 at the end of the same still retain the end of the paper ready to apply the same to the next blank in the manner described. To prevent too great a lift of the yoke arm, the rack 92 is quite short, as it only requires a partial revolution of the shaft 88 to raise said yoke arm to the necessary height, and when the pinion is disengaged from the rack, the rack arm will be held by the guard 93. The next thing to be done is to turn in against the walls of the blank the projecting edges of the paper covering the same, and this is accomplished in the following manner: Arranged to move with respect to the blank and at right angles to the frame 10 are a pair of frames 8& and 85, secured together and spaced the proper distance apart by means of adjusting screws 95. These frames have project-ions or feet 96 adapted to grooves 97 in the bed or table 1, and are moved by arms 98 connected to eccentrics 99, mounted on a shaft 100 which is driven by the bevel gears 101 and 102, the latter mounted on the shaft 6 carrying the pinion 6 which is driven by the rack 9.

The frame 84: has a series of radially movable arms 105, each of which is provided with pins or projecting members 106; said frame being so mounted as to be brought into a position surrounding the box blank. The arms 105 carrying the pins 106, are normally in the retracted position until said frame is brought into such position with respect to the projecting edges of paper that when said members are radially moved they will turn said paper over substantially at right angles to the side walls of the blank. To accomplish this, I provide cams 107 for engagement with said arms to move them in one direction; springs 108 being arranged to move them in the opposite direction. These cams are carried by shafts 109 journaled in the frame 8 1 and driven from each other by bevel gears 110; motion being imparted to one of said shafts by means of a pinion 111, which is brought into engagement with a fixed rack 112 when the frame 8 1 is moved forward. The frames 84 and 85 are then moved forward to their full extent so that the chuck carrying the blank is engaged by a wall 115 carried by the frame 85, which moves said chuck and blank into engagement with the plunger which enters the box and presses down the turned-over edge of paper against the inner wall of the same, holding the paper in such position until it has engaged said wall. The pins 106 are held in engagement with the paper during this action, and to permit the plunger 70 to operate, it is slotted at 116 for the passage of said pins. lVhile this turning in of the paper is taking place, the bottom of the box is disposed opposite the frame 85 carrying rollers 117 which are radially movable and which are arranged to be moved out againstthe projecting portion of the paper at the bottom of the box and lay the same down against said bottom; said rollers being operated simultaneously, or independently in pairs, so that the action of one pair will not interfere with the action of the other pair. These rollers are operated by cams 118 driven in the same manner as the cams 107, and springs 119 are provided to hold them in the inactive position. The blank having now been covered with paper, the several elements are retracted; the covered box removed, and a fresh blank applied to receive the covering in the manner described.

The shears for severing the paper are operated by a foot or projection 120 carried by the fame 84 and arranged to engage the lower end of the lever 71 when said frame comes forward for the purpose of embracing the blank and turning in the projecting edge of the paper. This foot is so arranged that after it has actuated the shears, it will disengage from the lever 71 and slide under the same, whereupon the shears will open. On the retraction of said frame, said foot 120 will be carried back and will be in position for operation of the shears when the frame 84- comes forward again.

In order to move the yoke arm 31 to the position shown in dotted lines, Fig. it must pass the projections l-T carried by the rod to and to permit this action, the arm has an offset portion 121 slotted at 122 so that when moved to said dotted position, it will not interfere with the projections.

While I have shown the frame 10 as actuated by a pair of links 18 from the face plates 16, it will be understood that a single face plate may be employed, having a single link centrally disposed with respect to said frame and connected thereto. The cam slots 58 of the frame 10 have the vertical portions so as indicated, permitting downward move; ment of the stripper member 56 when said vertical portion is brought opposite the projections 57 of the same, and this action takes place during the rearward movement of the frame 10. Upon the forward movement of this frame, the projections 57 must cross the gaps formed by the vertical portions of the cam slots, and to do this I provide bridge pieces 125 pivoted at 126 to the frame and normally upheld by means of springs 127. When these bridge pieces are engaged by the projections 57, they will be moved down to the position shown in Fig. 20, permitting the passage of said projections.

When the chuck carrying the paper blank is moved toward the plunger for the purpose of turning in the projecting edges of the paper, it compresses the spring 128, which will return said chuck to its normal position opposite the paper strip ready to receive another blank to be covered.

As the table 1 upon which the mechanism forming the subject of my invention is mounted is somewhat broad in its expanse, it desirable to support the same, and for this purpose I have shown rollers 130'adapted to suitable rails; that adjacent the periphery of the table being indicated at 181, while the others may be the supports for the racks 7, 8 and i).

The mechanism forming the subject of my invention is mounted upon a rotatable table, which, as described, is circular in form; and in the present instance carries three sets of such mechanism. To operate these several structures, the table is rotated by suitable means so that the pinions carried thereby are brought into contact with fixed racks disposed beneath the same, and these racks are so arranged that the actuation of the several parts of the mechanism will be synchronous for the purpose of carrying out the operation of covering boxes at three separate points.
